The Broad Museum is about to open its doors this September, and by doing so it's going to explode a U.S. military style daisy cutter on the Los Angeles art scene. Then comes Hauser Wirth and Schimmel (HWS) a few blocks away in LA's undeniably burgeoning Arts District.

The supremely delightful Alex Da Corte's Die Hexe (The Witch) at Luxembourg and Dayan Gallery is surely the most engaging exhibition to emerge on the Upper East Side or anywhere in Manhattan in quite a while. It is not too late to scoop this last Easter Egg out of the basket.

No surprise: the Museum of Modern Art has extended its exhibition of Matisse's cut outs as a result of popular demand. The same happened when the show featuring the master's late in life career debuted in London's Tate.

American artist Richard Prince's current show at Gagosian Gallery in New York, "New Portraits," features 37 images taken from other peoples' Instagram accounts, which have been enlarged to roughly 4 x 6 feet and printed on canvas.
